I think YouTube is the answer, as always, anyway by polishing I intend making your game more refined in various aspects!
I'm sure you can find many guides on the web easily! :)
Nothing to change in the mechanics!
It's peculiar, I've played 10 lying platforms, basically the same idea over and over, yours is pretty different which is a good thing!
The best thing you should improve, in my opinion, is polishing your game more, it depends on the time you can dedicate to it of course, anyway for the next Jam try to make it a bit longer, with more mechanics and maybe dare more with the graphics! :)
The idea was good, keep it up man!
Pretty interesting way of reinvent "Rock Paper Scissors", also loved the pixel graphics!
The only thing is find miscalculated here is in the Theme because as long as you don't have any possible way to figure out whether the computer is lying to you or not, the game is reduced to a complete random bunch of inputs...
I found that kinda fun because I tryed to understand the logic behind the computer advices but felt sort of betrayed when I didn't find any! D:
Anyway if you want to try and rate my game i post here the link because, I don't know why, itchio isn't showing my submission: https://itch.io/jam/cgj/rate/477069
